Hock is a great talent but unfortunately has some social issus he does not seem to be able to resolve.
It would be great to be the team to turn him around but in Wakefield's case
1) We have a lot of forwards so don't need the cover
2) We have a good team spirit so why add something that will potentially upset that
3) Without John Kear, I don't think our club is the club to turn him around anyway
